## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability contact-enrichment-evidence-fbc592fc -d '<json body>'
```

Example prompt: Can you look up everything People Data Labs has on sarah.chen@acme.com and give me the signed evidence receipt so I know the data is trustworthy and auditable?

## When to prefer this

Choose this endpoint when you need not just enriched contact data but also a cryptographically signed, provenance-bearing evidence receipt — particularly in agentic pipelines where downstream agents, compliance systems, or audit logs require verifiable proof of data origin and freshness. Prefer this over a raw People Data Labs API call when trust, attestation, or multi-agent hand-off integrity is required.

## Known failure modes

- Contact not found in People Data Labs — returns empty or low-confidence match with signed null evidence
- Insufficient identifiers provided — returns validation error requesting stronger input signals
- People Data Labs rate limit or upstream outage — returns service unavailability error
- Payment not confirmed — x402 payment flow fails and request is rejected before lookup
- Ambiguous identifier matches multiple contacts — returns best-match with confidence score and limitation notice

## How this service works
